Slave amplifiers are designed to be used with another 'Master' amplifier and provide extra power to a pre-existing audio system to allow more speakers to be connected. Great for larger installations where you need extra speakers and power, our slave amps will enhance and expand your existing commercial audio system.

A slave amplifier can be used as a standard power amplifier, but it lacks a preamp which means little to no controls. To use slave amps effectively, you would need to pair them with another amplifier that has a 'Slave' output on it. This acts as added power to the main amplifier which allows the addition of more speakers to your system, and this is ideal if you are expanding your system into more spaces.

There are two types of slave amplifiers that we offer. These are stereo amplifiers and 100V line amps. With stereo slave amps there are two outputs and volume controls and are meant to be used to add an extra two speakers to an audio system. They will usually be used with higher power speakers like wall-mounted ones, or any setup where there aren't a large number of speakers in total but more power is required.

100V line slave amplifiers are best implemented into systems that have a larger amount of speakers. If you have an installed audio system and need to add more speakers but your current amplifier isn't capable of providing the extra power needed for them, a 100v line slave amp will be perfect as you don't need to change your current system completely, you can simply install another amplifier as an add-on.
